Frequently asked questions
Is it momentary or latching?
It is ON-ON, which means it latches: each press changes the state and it stays in that state until pressed again.
Can it switch mains-powered loads?
It is rated 5A at 250V. Make sure your load and wiring stay within that rating and follow electrical safety practice.
